Description

Technical Field

[0001] This utility model relates to an evaporator, and more particularly to an evaporator with a fluid ring fully surrounding it, belonging to the technical field of evaporation and concentration equipment. Background Technology

[0002] In the production processes of industries such as chemical, pharmaceutical, and food brewing (e.g., winemaking), it is often necessary to use evaporators (or steamers) to distill, concentrate, or purify liquid materials in order to separate the target components or remove excess solvents.

[0003] Traditional evaporators (steamers), lacking the surrounding fluid of water, typically employ direct heating methods (such as bottom open flame heating or electric heating elements directly contacting the bottom of the tank). This heating mode results in concentrated and intense heat transfer, easily leading to localized temperature spikes or excessive fluctuations. Furthermore, the absence of a fluid-enclosed, balanced thermal environment in traditional evaporators results in a significant temperature gradient—the bottom heating zone is excessively hot, while the upper tank and sealed area are relatively cold. This temperature difference causes the steam generated by the evaporation of the material to condense prematurely before fully exiting the equipment due to contact with the cooler upper cover. The condensed liquid then falls back into the tank, creating an inefficient "evaporation-condensation-fallback" cycle. This phenomenon not only reduces evaporation efficiency but, more seriously, disrupts the reaction equilibrium of the material, leading to decreased chemical reaction stability (such as incomplete conversion of target components) and significantly increasing the uncontrollability of product quality. Taking the distillation process as an example, low-boiling-point harmful substances such as methanol should be discharged with the steam and separated. However, if the steam condenses and falls back prematurely due to the low temperature at the top, methanol will be mixed back into the liquor, affecting the safety and quality of the product.

The rear end of the first tank body 1 is provided with a first pin seat 104, and the first sealing cover 2 is provided with a first pin 105 that rotatably cooperates with the first pin seat 104. Figure 3 and Figure 4As shown, the first tank 1 has a support frame 3 inside, and a second tank 4 is detachably mounted on the support frame 3. Further, the support frame 3 includes an annular ring 301, an annular base 302, and a support leg 303. The upper end of the support leg 303 is vertically connected between the annular ring 301 and the annular base 302, and the lower end of the support leg 303 has a support base plate 304. The inner side of the annular base 302 has a cross-shaped reinforcing rib 305. An annular mounting plate 306 is provided on the cross-shaped reinforcing rib 305, and the annular mounting plate 306 has multiple mounting holes 307 for bolting connection with the second tank 4. The annular ring 301, annular base 302, and support leg 303 of the support frame 3 are made of carbon steel and then galvanized to improve structural strength and rust resistance. The top of the second tank 4 has a second sealing cover 5 that seals with the second tank 4. The first tank body 1, the second tank body 4, the first sealing cap 2, and the second sealing cap 5 are made of 304 stainless steel, which has good corrosion resistance and thermal conductivity, and is suitable for chemical, food and other industries. Preferably, the lower end face of the second sealing cap 5 is provided with a second annular sealing groove, and the top port of the second tank body 4 is provided with a second annular sealing flange 501 that mates with the second annular sealing groove. A second sealing ring 502 is also provided between the second annular sealing flange 501 and the second annular sealing groove. The second sealing cap 5 and the second tank body 4 employ a three-stage seal. The second annular sealing groove and the second annular sealing flange 501 form a mechanical engagement, with the second sealing ring 502 made of fluororubber pressed in between. The second sealing ring 502 ensures the airtightness of the distillation chamber 6. The front end of the side wall of the second tank body 4 is hinged to a second rotating component 401 via a pin. A second locking hook 402 is hinged to the second rotating component 401. The front end of the side wall of the second sealing cover 5 is provided with a second hook end 403 that mates with the second locking hook 402. The rear end of the second tank body 4 is provided with a second pin seat 404, and the second sealing cover 5 is provided with a second pin 405 that rotatably mates with the second pin seat 404. A distillation chamber 6 for containing the distillate is formed between the second sealing cover 5 and the second tank body 4. A first connecting port 7 communicating with the distillation chamber 6 is provided through the upper end of the second sealing cover 5. A second connecting port 8 is provided through the upper end of the side of the first tank body 1. A connecting pipe 9 is threadedly connected between the first connecting port 7 and the second connecting port 8.

A third sealing ring 701 is provided at the connection between the connecting pipe 9 and the first connecting port 7, and a fourth sealing ring 801 is provided at the connection between the connecting pipe 9 and the second connecting port 8. The first sealing ring 202, the second sealing ring 502, the third sealing ring 701, and the fourth sealing ring 801 are all made of food-grade silicone, which is heat-resistant (up to 200℃) and has good elasticity to ensure a sealing effect. A heating chamber 10 is formed between the first tank 1 and the second tank 4. A heating rod 11 is provided on the side of the first tank 1, and the heating end of the heating rod 11 extends into the heating chamber 10. The heating rod 11 is a commercially available electric heating rod 11 with a power of 3kW, a voltage of 220V, and a heating temperature range of room temperature to 150℃. It can be equipped with a thermostat to achieve precise temperature control. The heating end of the heating rod 11 is inserted into the heating chamber 10, and the water in the heating chamber 10 is used as the heat transfer medium to achieve uniform heating of the second tank 4.

[0023] This invention achieves uniform heating of the second tank 4 by forming an annular heating chamber 10 between the first tank 1 and the second tank 4 and installing a heating rod 11. This increases the effective heat transfer area and allows for control of the distillation temperature, ensuring uniform heat transfer to the distillate within the distillation chamber 6. It also prevents steam from condensing and falling back during evaporation, thereby improving evaporation efficiency and energy utilization. This invention employs multiple sealing rings (first sealing ring 202, second sealing ring 502, third sealing ring 701, and fourth sealing ring 801) and sealing structures (first annular sealing groove, first annular sealing flange 201, second annular sealing groove, and second annular sealing flange 501) to effectively block steam leakage channels, reduce energy waste, and maintain stable pressure and temperature within the evaporator. The first sealing cover 2 and the first tank 1, second sealing cover 5, and second tank 4 all utilize a hinged and locking hook quick-opening and closing structure, combined with annular sealing grooves and sealing rings, ensuring both sealing performance and rapid opening and locking. The connecting pipe 9 of this utility model adopts a corrugated pipe structure, which has a certain degree of flexibility and can adapt to slight assembly deviations during installation, reducing the requirements for installation accuracy. At the same time, the corrugated pipe can absorb the vibration generated during equipment operation, preventing the rigid pipe from loosening or breaking due to vibration, and reducing the risk of pipe damage. In addition, the cross-shaped reinforcing ribs 305 of the support frame 3 and the support base plate 304 can enhance the overall structural stability, prevent the components from deforming due to shaking during equipment operation, and further extend the overall service life of the equipment.

[0024] Work process Unlock the first locking hook 102 at the front end of the side wall of the first tank 1 (rotate around the hinged first rotating member 101 to disengage from the first hook end 103), grasp the handle 12 at the top of the first sealing cover 2, and flip the first sealing cover 2 upward around the first pin 105 at the rear end (which engages with the first pin seat 104), thereby opening the inner cavity of the first tank 1. Then operate the second tank 4, similarly unlocking the second locking hook 402 at the front end of the side wall of the second tank 4, and flipping the second sealing cover 5 (rotating around the second pin 405) to completely open the distillation chamber 6 of the second tank 4 (the space enclosed by the second tank 4 and the second sealing cover 5). Add distillate into the distillation chamber 6, and then close the second sealing cover 5 around the second pin 405, so that the second annular sealing flange 501 at the top of the second tank 4 is embedded in the second annular sealing groove of the second sealing cover 5, and the second sealing ring 502 in the groove is squeezed; rotate the second locking hook 402 to fasten the second hook end 403, ensuring that the distillation chamber 6 is completely sealed. Next, water is injected into the annular heating chamber 10 between the first tank 1 and the second tank 4, ensuring the water level covers the second sealing cap 5. Then, the first sealing cap 2 is closed, causing the first annular sealing flange 201 of the first tank 1 to embed into the first annular sealing groove of the first sealing cap 2, compressing the first sealing ring 202; the first locking hook 102 is then locked, completing the sealing of the heating chamber 10. The power supply to the heating rod 11 is then turned on, and the heating end of the heating rod 11 directly heats the water inside the heating chamber 10. Since the heating chamber 10 is annular and completely surrounds the second tank 4, the heat transfer medium forms a uniform "fluid heat ring" after being heated, and the heat is smoothly transferred to the distillate in the distillation chamber 6 through the side wall of the second tank 4. The distillate in the distillation chamber 6 evaporates stably under the action of uniform heat, and the generated steam, due to the uniform temperature of the distillation chamber 6, will not condense and fall back on the inner wall of the second sealing cap 5, but will continue to accumulate upwards and enter the connecting pipe 9 through the first connecting port 7 on the second sealing cap 5. After the steam is discharged from the second connection port 8 through the connecting pipe 9, it can be connected to the subsequent condensing device (such as a condenser) or collection system (such as a liquid storage tank) to achieve the separation of target components (such as separating low-boiling-point impurities such as methanol during distillation, and separating solvent vapors in chemical production), avoiding the ineffective cycle of traditional "evaporation-condensation-fallback" and improving evaporation efficiency.

[0025] In summary, this invention ensures uniform heat transfer to the distillate by fully enclosing the distillation chamber and avoids condensation and fallback of steam during evaporation, thereby improving evaporation efficiency and energy utilization.
